Working Principles
The MAX706REUA+T is a voltage supervisor IC that ensures proper operation of microprocessors by monitoring the supply voltage and microprocessor activity. It generates a reset signal when the supply voltage rises above the reset threshold voltage, providing a power-on reset function. Additionally, it includes a watchdog timer that monitors the microprocessor's activity by checking the state of the watchdog input. If the microprocessor fails to toggle this input within the specified timeout period, the MAX706REUA+T generates a reset signal to restart the system.
